Half-Life Walkthrough

Xen

The oh so wonderful jumping puzzles continue. Here on this alien world, you'll need to make liberal use of that long jump module. Use it to leap from platform to platform, and then jump onto one of the moving platforms when it comes close.

Make your way down onto the bottom bun of the big alien hamburger and find a little crack in a wall that you'll find. Outside it you'll see a little pool of water which emits a strange noise and has little snowflakes that appear and disappear around it. If you stand in it, you'll slowly regain health; a very good thing when you see what's coming up soon.

Inside the crack is a big room with three strange mushroom-type things. "Use" all three to open up little receptacles on top of them, then crack open the viney cage holding three little floating butterflies. Through some sort of alien magic a new portal will open for you to enter.
